Video 2: The Elegant Universe Einstein's - Relativity
Before watching
What is gravity?
It is the force of attraction between two objects.
Who discovered it?
This was discovered by the scientist Isaac Newton.
How does the Einstein’s Relativity Theory relate with gravity?
I think that the Einstein’s Relativity Theory examines the difference between acceleration and gravity.
Mention five words you might find in the video
Gravity
Bodies
Earth
Objects
Physical
Attraction
2. Which of the words in the question above did you find in the video? List them The words that appear are: Gravity Earth Objects Attraction
3. What was the embarrassing secret Newton was holding about gravity? He had no idea how gravity actually works.
4. The narrator presents some examples in the video. What happens in the first one? What happens to the sun and planets? Explain In the first example he shows what could happen if the sun disappear. He says different about Newton’ theory and Einstein’ theory Newton says if the sun vaporizes and completely disappears the planets would immediately ply out their orbits careening. In other words Newton thought that gravity was a face and so we would immediately feel the effect of the sun’s destruction. But Einstein saw a big problem with Newton’s theory. Einstein knew light doesn’t travel instantaneously. In fact, it takes 8 minutes for the sun’s rays to travel the 93 million miles to the earth. And since he had shown that nothing not even gravity can travel faster than light. How the earth could be released from orbit, before the darkness resulting from the sun’s disappearance, reached our eyes.
5. What happens in the second one? What happens to the sun and planets? Explain In the second picture Einstein explain the gravity does not exceed the cosmic speed limit. After 10 years Einstein found the answer and a new kind of unification. He talks about things moving along superficies in the space. This unifying fabric is worth and strength by heavy objects like planets and stairs. And this curving is what we feel as gravity if the sun disappear its form of wave that travel cross of space so we wouldn’t feel the change in our orbit around the sun until this wave reach the earth
6. Why was Newton’s idea of gravity incorrect for Einstein? Newton’s theory predicts that with the destruction of the sun the planets would immediately fly out of their orbits careening off into space. He thought that gravity was a force that instantaneously across any distance.
7. What is the final definition of gravity given in the video? It’s worth in curves in the fabric space-time.
8. What’s the name Einstein gave to it? He called theory of relativity.
9. What’s the difference between Newton’s gravity and Einstein’s gravity? The difference is that Newton thought the gravity action move in a infinity speed. Example if the sun disappear the earth feels immediately this is impossible cause we know that the speed of light. Einstein says that light taken few minutes to feel.
